JEFFREY JOHN WALLACE, 0F AMrrE, LOUISIANA,- AssIcrNon 'ro GULLETT GIN cora- PANY, or AMITE, LOUISIANA END noon. LIFT MECHANISM Application fi1ed June 15,

' hinged front and rear doors, and are held in place by channels fixed to the front and rear doors and overlapping the side edges of the end doors. When the side doors are opened after a baling operation, the press operator must lift these end doors out bodily from the press and place them aside until the press is to be prepared for another operation. 1

In the latest type modern presses, these doors are very heavy. The matter of re-' moving and replacing them is, therefore, a time consuming and expensive task; and some mechanical means is therefore desirable to effect their manipulation.

The main object of the present invention,

therefore, is to provide baling presses with a simple and inexpensive means for handling these heavy end doors both in placing them in proper place in the press and removing them when desired.

Other objects of the invention will become apparent as the description proceeds.

In the drawings:

Figure 1 is a front elevation of a double up-packing baling press, showing one box thereof below the tramper, and the other box with the front and rear doors lowered and end doors held to permit removal of a wrapped bale;

Figure 2 is a fragmentary perspective of the present invention as applied to an end door of a cotton press;

Figure 3 is a horizontal section through a press box taken above the end door op-.

erating mechanism;

Figure 4 is a fragmentary vertical sectional elevation through one corner of the press box, showing front and end doors closed; and

Figure 5 is a vertical section showing an end door in open position.

Referring to the drawings:

The invention is shown, particularly in Figure 1, as applied to the press boxes of a double revolving lip-packing baling press.

192$. Serial No. 285,744.

The press boxes 1 and 2 revolve abouta central standard 28 to bring each box alternately under a tramper 4 and above a. hydraulic ram 5. r

The press box 2 is shown in Figure 1 in closed position and with the part disposed so as to receive cotton from the tramper a preparatory to being baled and wrapped. The

press box 1 is shown with the front and-rear doors thereof swung about'their hinges to a horizontal position, and with the end doors swung upwardly and outwardly from contact with the bale of cotton to facilitate wrapping of the bale and to permit removal of the wrapped bale from the press.

The front door is designated by the reference numeral 6 and each of the end doors is designated by the reference numeral 7 Since each of the end doors is operated by identical lifting mechanism a detailed description of one door with the mechanism connected thereto will be suflicient to disclose the invention; and the corresponding parts ofthis mechanism will be identified by the same reference numerals'wherever shown in the several figures of the drawings. I

Referring particularly to'Figure 2, there is shown one of the end doors 7 having a beveled lower edge 25 and secured adjacent thereto a pair of hook members 8 and 9 provided with bent over'lugs 10 and 11, respectively, to receive a crank arm 12 formed between alined bearing parts '13 and 14 of a rod 15 adapted to be rotated about said bearing parts 13 and 14c to lift the door 7 upwardly and its beveled edge 25 engaging lugs 20 and outwardly from the press box.

The part 1 1 has a handle extension 16 ex tending therefrom; and the parts 13 and 14 are journaled inbearings 17 and 18 formed in brackets 19 and 20, respectively, which are secured suitably to the web 21 of a channel iron 22 extending across the end of the press box.

It is to be noted thatthe lugs- 10 and 11 U disassembled by merely lifting the door away from the rod 16.

As shown particularly in Figures 4 and 5, the members 16, lugs 10, and brackets 19 and 20, are so proportioned that when the door 7 is raised from closed position, shown in Figure 4:, to the open position, shown in Figure 5, the door 7 has its lower end supported by the brackets 19 and 20 in such position that the dooris held open by gravity.

The end doors 7 on opposite sides of the pivot standard 23 are moved into and out of operative position by crank arm mechanism identical with the mechanism on the other end doors, except that brackets 19 and 20 are replaced by small standards 20, identical in their slotted bearing ends with brackets 19 and 20 and suitably secured to a supporting plate 24 connecting the press boxes 1 and 2. These intermediate end doors are operated in exactly the same manner as the outer end doors.

It will be apparent from. the disclosure that I have provided an exceedingly simple and inexpensive mechanism for raising and lowering the heavy end doors of cotton baling presses and which enables the doors to be readily removed from the press by merely lifting them off the crank arms 12. It will also be apparent from the drawings that when the lever arms 16 are operated to lift the doors to open position, the doors will stay open by their own weight resting on the brackets 19 and 20 until the levers 16 are operated in the opposite direction to move the end doors into closed position.

- What I claim is:

1. In a cotton baling press, supporting framework, a pair of side doors hinged to said framework, a pair of end doors movable bodily into and out of position between said side doors to form therewitha baling box, brackets fixed to said framework below the lower ends of said end doors having upwardly open notches, lugs fixed to the lower ends of said doors having downwardly open hooks, and crank shafts bearing in said bracket notches and lug hooks to lift said end doors and move them outwardly from baling position.

2. The combination set forth in claim 1, in which the parts are relatively proportioned so that the lower ends of the end doors when in open position rest on said brackets and have their upper ends supported by said framework.

3. In a cotton 'baling press, supporting framework, a press box having a bodily movable end door, lugs 'secured'to the lower end of said door and each shaped to form anopen hook, brackets fixed to the framework and having open notches formed in the ends thereof and a crank shaft seated in said hooks and slots to move said door bodily into and out of a predetermined location in said box.

a beveled lower edge, a pivot member located on the press adjacent the bottom of the door and spaced outwardly from that face of the press and means bearing on that pivot for lifting and rocking .the door upwardly and outwardly .until its bottom edgeengages the pivot member to secure same in opened position.

In testimony whereof I aflix my signature.

JEFFREY JOHN WALLACE.
